Hidden Modifier Groups

Description:
The ability to configure modifier groups so they do not appear in the UI for customers or operators during the ordering process but are still included on printed or digital receipts. This can be useful for backend operations, item bundling, or ensuring specific items are communicated clearly to the kitchen or staff without cluttering the ordering interface.

Use Case Example:

A fast food restaurant wants to include "Add Chips" on the receipt to inform the kitchen but does not want the customer to see or select this option in the UI.
This could also apply to automatic inclusions like sauces or sides that are part of a meal by default but don't require explicit selection.
